This third edition of Paul Murrell's classic book on using R for graphics represents a major update, with a complete overhaul in focus and scope. It focuses primarily on the two core graphics packages in R - graphics and grid - and has a new section on integrating graphics. This section includes three new chapters: importing external images in to R; integrating the graphics and grid systems; and advanced SVG graphics. The emphasis in this third edition is on having the ability to produce detailed and customised graphics in a wide variety of formats, on being able to share and reuse those graphics, and on being able to integrate graphics from multiple systems. This book is aimed at all levels of R users. For people who are new to R, this book provides an overview of the graphics facilities, which is useful for understanding what to expect from R's graphics functions and how to modify or add to the output they produce. For intermediate-level R users, this book provides all of the information necessary to perform sophisticated customizations of plots produced in R. For advanced R users, this book contains vital information for producing coherent, reusable, and extensible graphics functions.

This textbook presents an introduction to generalized linear models, complete with real-world data sets and practice problems, making it applicable for both beginning and advanced students of applied statistics. Generalized linear models (GLMs) are powerful tools in applied statistics that extend the ideas of multiple linear regression and analysis of variance to include response variables that are not normally distributed. As such, GLMs can model a wide variety of data types including counts, proportions, and binary outcomes or positive quantities. The book is designed with the student in mind, making it suitable for self-study or a structured course. Beginning with an introduction to linear regression, the book also devotes time to advanced topics not typically included in introductory textbooks. It features chapter introductions and summaries, clear examples, and many practice problems, all carefully designed to balance theory and practice. The text also provides a working knowledge of applied statistical practice through the extensive use of R, which is integrated into the text. Other features include: * Advanced topics such as power variance functions, saddlepoint approximations, likelihood score tests, modified profile likelihood, small-dispersion asymptotics, and randomized quantile residuals * Nearly 100 data sets in the companion R package GLMsData * Examples that are cross-referenced to the companion data set, allowing readers to load the data and follow the analysis in their own R session

Data science unifies statistics, data analysis and machine learning to achieve a better understanding of the masses of data which are produced today, and to improve prediction. Special kinds of data (symbolic, network, complex, compositional) are increasingly frequent in data science. These data require specific methodologies, but there is a lack of reference work in this field. Advances in Data Science fills this gap. It presents a collection of up-to-date contributions by eminent scholars following two international workshops held in Beijing and Paris. The 10 chapters are organized into four parts: Symbolic Data, Complex Data, Network Data and Clustering. They include fundamental contributions, as well as applications to several domains, including business and the social sciences.

IT-Projekte haben in vielen Unternehmen eine zentrale Bedeutung. Sie binden Ressourcen und generieren entsprechende Kosten. Im Durchschnitt werden in Unternehmen 33 Projekte pro 1000 Mitarbeitern durchgefuhrt und pro Mitarbeiter und Jahr EUR 8.000 in IT-Projekte investiert. Von diesen Projekten werden weniger als die Halfte erfolgreich abgeschlossen.

An theoretischem Wissen respektive an der Ausbildung kann es nicht liegen. Aus Sicht der Autoren fehlt es den Projektmanagern oft an der notwendigen Reflexion, dies besonders wenn die Projekte in kritische Phasen treten. Ein Erfahrungsaustausch zwischen den Projektleitern findet vielfach aus zeitlichen Grunden nur unvollkommen statt. Hier setzen die Autoren an. Sie legen das Schwergewicht auf die kritischen Erfolgsfaktoren eines IT-Projekts. Gegliedert nach Erfolgsfaktoren fuhrt das Buch zum Thema und veranschaulicht Losungswege anhand von Beispielen aus der Praxis.

Real-Time Enterprise (RTE) ist eine Unternehmensstruktur, die durch kontinuierliche Beschleunigung der Managementprozesse die eigene Aktions- und Reaktionsgeschwindigkeit nachhaltig verbessert und verzogerungsfrei auf externe sowie interne Anderungen reagieren und damit Zeit und Kosten einsparen kann. Voraussetzungen und Rahmenbedingungen hierfur sind durchgangig integrierte Geschaftsprozesse und Informationsflusse entlang der kompletten Wertschopfungskette. Im Idealfall sind dabei alle Arbeitsprozesse in einem Unternehmen optimal aufeinander abgestimmt, so dass Data Warehouse, Supply Chain Management, Customer Relationship Management und Enterprise Resource Planning wirkungsvoll ineinander greifen. Dabei endet die Betrachtung von Prozessen und Informationen nicht an den Unternehmensgrenzen. Statt dessen sind Kunden und beteiligte Partnerfirmen beziehungsweise deren Prozesse transparent eingebunden und tauschen Informationen uber alle relevanten Ereignisse zeitnah aus. "

This book introduces econometric analysis of cross section, time series and panel data with the application of statistical software. It serves as a basic text for those who wish to learn and apply econometric analysis in empirical research. The level of presentation is as simple as possible to make it useful for undergraduates as well as graduate students. It contains several examples with real data and Stata programmes and interpretation of the results. While discussing the statistical tools needed to understand empirical economic research, the book attempts to provide a balance between theory and applied research. Various concepts and techniques of econometric analysis are supported by carefully developed examples with the use of statistical software package, Stata 15.1, and assumes that the reader is somewhat familiar with the Strata software. The topics covered in this book are divided into four parts. Part I discusses introductory econometric methods for data analysis that economists and other social scientists use to estimate the economic and social relationships, and to test hypotheses about them, using real-world data. There are five chapters in this part covering the data management issues, details of linear regression models, the related problems due to violation of the classical assumptions. Part II discusses some advanced topics used frequently in empirical research with cross section data. In its three chapters, this part includes some specific problems of regression analysis. Part III deals with time series econometric analysis. It covers intensively both the univariate and multivariate time series econometric models and their applications with software programming in six chapters. Part IV takes care of panel data analysis in four chapters. Different aspects of fixed effects and random effects are discussed here. Panel data analysis has been extended by taking dynamic panel data models which are most suitable for macroeconomic research. The book is invaluable for students and researchers of social sciences, business, management, operations research, engineering, and applied mathematics.

To date, statistics has tended to be neatly divided into two theoretical approaches or frameworks: frequentist (or classical) and Bayesian. Scientists typically choose the statistical framework to analyse their data depending on the nature and complexity of the problem, and based on their personal views and prior training on probability and uncertainty. Although textbooks and courses should reflect and anticipate this dual reality, they rarely do so. This accessible textbook explains, discusses, and applies both the frequentist and Bayesian theoretical frameworks to fit the different types of statistical models that allow an analysis of the types of data most commonly gathered by life scientists. It presents the material in an informal, approachable, and progressive manner suitable for readers with only a basic knowledge of calculus and statistics. Statistical Modeling with R is aimed at senior undergraduate and graduate students, professional researchers, and practitioners throughout the life sciences, seeking to strengthen their understanding of quantitative methods and to apply them successfully to real world scenarios, whether in the fields of ecology, evolution, environmental studies, or computational biology.

Das Buch wendet sich an IT-Entwickler, Projektmanager und CIO's. Hauptthema ist die gezielte Entwicklung von F higkeiten (Skills) jenseits der klassischen "IT-Denke." Fakt ist, dass laut statistischer Erhebungen ber 60 Prozent aller Software-Projekte nicht zum gew nschten Erfolg f hren, d.h. nicht in Budget, Zeit oder Qualit t zur Auslieferung kommen. Wenigstens die H lfte dieser Projektfehler geht zu Lasten fehlender Skills der verantwortlichen IT-Profis. Der international erfahrene Autor arbeitet diese Problematik auf, stellt hierzu die entsprechenden Themenschwerpunkte sehr praxisnah in den Mittelpunkt und benennt konstruktive L sungen.

This book is intended for someone learning functions of a complex variable and who enjoys using MATLAB. It will enhance the exprience of learning complex variable theory and will strengthen the knowledge of someone already trained in ths branch of advanced calculus. ABET, the accrediting board for engineering programs, makes it clear that engineering graduates must be skilled in the art of programming in a language such as MATLAB (R). Supplying students with a bridge between the functions of complex variable theory and MATLAB, this supplemental text enables instructors to easily add a MATLAB component to their complex variables courses. A MATLAB (R) Companion to Complex Variables provides readers with a clear understanding of the utility of MATLAB in complex variable calculus. An ideal adjunct to standard texts on the functions of complex variables, the book allows professors to quickly find and assign MATLAB programming problems that will strengthen students' knowledge of the language and concepts of complex variable theory. The book shows students how MATLAB can be a powerful learning aid in such staples of complex variable theory as conformal mapping, infinite series, contour integration, and Laplace and Fourier transforms. In addition to MATLAB programming problems, the text includes many examples in each chapter along with MATLAB code. Fractals, the most recent interesting topic involving complex variables, demands to be treated with a language such as MATLAB. This book concludes with a Coda, which is devoted entirely to this visually intriguing subject. MATLAB is not without constraints, limitations, irritations, and quirks, and there are subtleties involved in performing the calculus of complex variable theory with this language. Without knowledge of these subtleties, engineers or scientists attempting to use MATLAB for solutions of practical problems in complex variable theory suffer the risk of making major mistakes. This book serves as an early warning system about these pitfalls.

All the Essentials to Start Using Adaptive Designs in No Time Compared to traditional clinical trial designs, adaptive designs often lead to increased success rates in drug development at reduced costs and time.
